CRYOGENIC POWER GENERATING PLANT AND TURBINE USED THEREIN Russian patent published in 2024 - IPC F01K25/10 F01D13/00 

FIELD: heat power engineering.

SUBSTANCE: group of inventions relates to heat power engineering, namely to cogeneration plants with closed circulation of working medium. Cryogenic power generating plant (CPGP) contains in-series connected and placed in one or more sealed heat-insulated housings storage capacity of liquid working medium (WM), evaporator with channels for supply and removal of heat carrier, a nozzle unit, a turbine with a generator, as well as a receiving device for liquid WM, which is connected to a container for its storage, wherein in each used housing there is a vacuum and a temperature not higher than the boiling point of the WM at pressure of 1 bar. Turbine is located above the evaporator and contains a bucket gas turbine installed on one vertical shaft and a jet liquid turbine of the Segner wheel type, containing a conical base, and curved throttling tubes fixed on it, ending with jet nozzles and having inner diameter of not more than 0.8 mm. Both turbines are connected by adapter in the form of bent cone, providing transition of working medium from gas turbine to throttling tubes.

EFFECT: higher energy efficiency.
